Renewable Energy:123

Despite all the recent negative publicity surrounding nonrenewable fuel sources, petroleum and natural gas have been advantageous for the growth of our modern world. It has actually helped the population have life after dark, transport of items all over the world, and permitted technology to advance. Nevertheless, using fossil fuels has also resulted in many negative consequences: it has developed extreme pollution, political problem, economic control and complete dependence of countries that lack this natural deposit.

The supply of nonrenewable fuel sources is limited, and it is only located in particular locations of the world. The demand for fossil fuels develops problems which threaten peace. Countries that have appropriate fossil fuel supplies might possibly threaten the security and economy of countries that depend on these countries. In addition, there have actually been numerous estimates made about the amount of fossil fuels left worldwide. These estimates are dependent upon the population growth, and just how much the actual non-renewable fuel source consumption increases in the near future. These estimates state that there is enough for approximately another 35 years of oil, 37 years of gas, and 107 years of coal [1] In addition to the negative environmental effects of using these fuels, there is a finite supply of nonrenewable fuel sources that will require using another form of energy. This limited supply and large demand will trigger inevitable price increases. Therefore, completion of inexpensive oil is rapidly approaching.

The use of nonrenewable fuel sources to meet the world’s energy requires is triggering unsafe side-effects for people, animals and plants. Waste products from these fuels, heat the earth’s atmosphere and contaminate the earth’s air, water, and ground. This results in minimizing living conditions for all types of the earth. In addition to being dangerous to our environment, and the health of lots of species, the pollution is likewise altering the atmosphere of the world. This trend is called global warming, and will continue to become worse due to the increase in the combustion of fossil fuels for electricity due to the growing world population. In the process of burning the gasoline, carbon monoxide, nitrogen oxides and unburned hydrocarbons are launched into the atmosphere. The catalytic converters decrease a large section of the pollution, but they are not good. Lots of cities presently have unsafe levels of ozone in the air. The world requires a power source that has low contaminant emissions, is energy-efficient, and has a limitless supply of fuel for a rising world population.

Can you believe this!

Oil and nonrenewable fuel sources are another big concern in our world today. Not only do we eat so much of it each day that the fumes given off from burning said fuels are damaging to the environment. Nonrenewable fuel sources are not an infinite natural resource that we have it is restricted.

Are You Serious?

Many alternative energy technologies have been researched and established. These consist of solar, wind, Bioenergy, geothermal energy in addition to many others. Solar cells use the sun to generate electricity, wind power is obtained from the kinetic energy of the wind, Bioenergy is extracted from plants and geothermal energy is energy from the earth. Each of these alternative energy sources has its downsides and advantages and all are in varying stages of development.

In a lot of countries around the world, if the supply of fossil fuels was cut off– the whole economy would come to a stop. There would not be a way for people to drive to work, or use electricity in their offices or houses. The global population consumes petroleum products at a rate 100,000 times greater than the rate that they are formed. The United States presently imports 70 % of the oil, and it is still enhancing. About 80 % of the complete energy in the world is provided by fossil energy sources [2] The International Energy Agency [3] estimates that the primary world demand for energy is anticipated to grow by about 45 % by 2030. The cost of meeting this energy demand is estimated to be $20 trillion U. S. dollars [2, 3] Therefore, considering that so much money needs to be invested on the investment in energy infrastructure in the approaching years, this enables a chance for replacing the fossil fuel infrastructure with a renewable energy infrastructure. U.S. coal and fossil fuel plants are currently fairly old for a minimum of half of the plants was developed prior to 1970. If the oldest plants are retired initially, it might be a simple progression to transfer the energy production of alternative energy without retiring the plant’s too soon.

Due to the fact that of the boom in solar power, power stations all over the world are not lucrative to operate, and renewable energy is beginning to show its strength as fossil fuels decline. Renewable resource plants are short on running expenses in comparison with nonrenewable fuel source generators.

Everybody is aware that the meaning of global warming is a significant increase in the Earth’s temperature over a short amount of time due to the outcome of human activities. An increase in temperature of 0.4 \u00b0 Celsius is significant over a century, and an increase of 1 \u00b0 Celsius is considered global warming. Although 1 \u00b0 or 2 \u00b0 Celsius may not seem like a lot, small temperature changes can have significant effects. When you hear the term “glacial epoch,” you probably think of the world covered in snow and ice. Ice ages happen every 50,000 to 100,000 years, and the average global temperature was just 5 \u00b0 C cooler than they currently are [4, 5, 6]

The Intergovernmental Panel on Climate Change (IPCC) is a group of over 2,500 experts from countries throughout the world that satisfied in 2007 to advance climate research. Among the conclusions of this meeting was that the last 15 years have been the warmest since 1850. A few of their observations were that glaciers and snow have reduced in the northern and southern hemispheres, and average frozen temperatures have enhanced by twice the global average during the last 100 years. Rain has enhanced in the Americas, northern Europe and parts of Asia, and South Africa and the Mediterranean have been experiencing drying out trends. Overall, hot days around the world have actually become more regular, and cold days have ended up being less regular and serious [4– 7]

Natural changes in climate such as heating due to volcanic activity, radiation from the sun, and changes in the chemistry of the atmosphere sometimes take countless years to change just 1 \u00b0 C. The present co2 concentration (CO2) figured out from the ice cores (180 to 300 ppm) is far greater than the natural array discovered over the last 650,000 years. The eventual rise in temperature would be around 2.4– 2.8 \u00b0 C [the CO2 concentration increases to 400– 440 ppm and stays there 4– 7]

In order to stabilize the CO2 level, it needs to come to a head, then decrease. The more quickly that this happens, the lower the peak stabilizing level. According to the IPCC, in order to support the CO2-equivalent concentrations around 445 to 490 ppm, CO2 emissions would need to peak by 2015 (at the latest), then, be up to in between 50– 85 % below the year 2000 levels by 2050. A later peak and greater concentrations would result in bigger increases in temperature.

In order to effectively have a society based upon renewable energy, there needs to be a way to establish energy for renewable energy (solar and wind power) is intermittent. Solar and wind energy are both exceptional approaches of obtaining energy from natural resources, however, the levels of sunshine, and the intensity of wind varies. When these sources are not readily available– electricity cannot be created. When a large amounts of energy are being produced, hydrogen can be created from water. The hydrogen can then be stored for later use.

As far as fuels are concerned, hydrogen is one of the most powerful fuels. Hydrogen is the most abundant aspect in the universe; nevertheless, it does not exist in its pure form on earth. It has actually to be drawn out from common fuel types or water. The process that is used most frequently for removing hydrogen is the steam reforming of natural gas. It can also be removed from coal, nuclear power, biofuels and even waste products. Hydrogen can likewise be produced, making use of water with the process of electrolysis. Electrolysis splits water into hydrogen and oxygen using electricity. Renewable forms of energy such as photovoltaic cells, wind, geothermal and hydro is significantly being utilized to produce electricity, and excess electricity can be made use of for the electrolysis process. The hydrogen can be used, or stored to generate electricity at a later time.

Electricity for residential and business use can be produced, making use of a mix of wind, solar, and hydrogen fuel cells. There will likewise have to be intermediate options and cooperation between corporations, utility companies, and individuals in order to effectively shift to a renewable, hydrogen, and energy-efficient economy. Corporations will need to make energy-efficient electronics and appliances, which reduce energy consumption, and automatically turn themselves off when not in use. Utilities and governments have to give rewards for people to use less energy, and individuals need to be more aware of the amount of energy that they are using. There is significant proof that the growth in the electricity demand can be decreased with the use of producing devices and devices that are more energy-efficient, carrying out building codes, monetary rewards and helping individuals to voluntarily decrease energy use.

Solar power is the most commonly known renewable types of energy. It can be made use of in both domestic and industrial scenarios. By using photovoltaic solar cells, it is possible to gather sufficient energy for 75 % -100 % of domestic requirements. It is possible to collect electrical energy along with glowing energy which permits the heating of water, for the generation of cool air, and more. Solar energy can also be made use of for floor-coil heating or to heat up the pool.

The U.S. Department of Energy recently conducted a research that examined wind power, and found that executing 600 GW by 2030 was possible. This would be an estimated 50 % of the United States forecasted power use in 2030 if this in fact occurred. One advantage of wind power is that it does not take a great deal of space– the towers can be put on farmland, (and almost anywhere else), without really getting in the way.

Solar photovoltaics (PV) are a technology that can be utilized quickly, and sales have been growing really strongly throughout the last decade. It still has a small market share due to the high costs of the solar panels. Focusing solar energy may be accepted quicker than standard solar technology due to the fact that the expenses are beginning to be competitive with traditional energy technologies. Concentrating solar energy systems allow power plants to produce electricity from the sun on a bigger scale, which in turn allows consumers to make the most of solar power without making the investment in personal solar technology systems. If it can be shown within the next couple of years, geothermal energy can also offer a significant amount of energy.

Fuel cells have currently been used for decades for business and domestic use. Fixed fuel cells can produce enough electricity and heat to power an entire house or business, which can result in significant savings– and they also can make more than enough power to sell a few of it back to the grid. Fuel cells can likewise assist offer electricity by working with large nuclear power plant to become more decentralized and increase efficiency. Most electricity produced by large fossil-fuel burning nuclear power plant are distributed with high voltage transmission wires over fars away. These power plants appear to be extremely reliable because of their large size; however, a 7 to 8 percent electric energy loss in Europe, and a 10 percent energy loss in the United States takes place during long distance transmission. Among the primary problems with these transmission lines is that they do not work appropriately all the time. It would be more secure for the population if electricity generation did not happen in several large plants, however is produced where the energy is needed. Fuel cells can be utilized any place energy is required without the use of large transmission lines.

Fuel cells can power houses and businesses where no electricity is available. Sometimes it can be extremely pricey for a house that is not on the grid to have actually the grid linked to it. Fuel cells are also more dependable than other industrial generators utilized to power houses and businesses. This can benefit lots of companies, offered just how much money they can lose if the power goes down for even a short time.

Yes, remain linked to the grid and send out a few of that extra power back to the grid. Supplying your neighbors with electricity and being paid for it is something that is possible, even likely when you are creating adequate power.

In the future, the energy economy, individual households will have the ability to produce their own energy. This will assist to redistribute power from global oil companies and governments to the people. Individual families can share their energy with the grid to assist disperse energy to areas that may have less due to weather elements.

Ocean energy is another popular renewable resource source which utilizes the power of the sea. With the use of existing power and sea thermal energy conversion, an enormous amount of energy is collected. Tidal and wave power is likewise an energy system used within ocean energy harnessing.

Solar energy is the most frequently known renewable forms of energy. It can be made use of in both industrial and domestic circumstances. With the use of photovoltaic solar cells, it is possible to collect more than enough energy for 75 % -100 % of domestic requirements. It is possible to collect electrical energy as well as radiant energy which allows for heating of water, for the generation of cool air, and more. Solar power can also be utilized for floor-coil heating or to warm pool.

The Energy Information Administration [2] states that vehicles use 70 % of the liquid fuels consumed by the U.S. The average fuel efficiency of current vehicles has to do with 22 miles per gallon. However, it ought to not be unlikely for the average fuel efficiency to increase to about 45 miles per gallon by 2030. Hybrid, electric and fuel cell vehicles would all supply either lower or no oil consumption, and each can be helpful in transforming to a hydrogen and renewable energy-based economy. All the significant automakers have currently invested heavily in hydrogen fuel cell technology vehicles.

Lots of aspects are contributing to the fuel cell push in the automotive market. The accessibility of nonrenewable fuel sources is limited, and due to this, an unavoidable cost increase will take place. In addition, legislation is becoming stricter about managing environmental emissions. One of the new pieces of legislation that will help present the fuel cell car market in the U.S. is the Californian zero emission automobile (ZEV) mandate, which requires that a particular variety of vehicles to be offered yearly in California. Fuel cell vehicles also have the capability to be more fuel-efficient than vehicles powered by other fuels. This power technology permits a new array of power use in small two-wheeled and four-wheeled vehicles, boats, scooters, unmanned vehicles, and other utility vehicles.

In the future, cars will be plugged into an outlet in houses and workplaces to assist generate electricity for both the vehicles and the houses. Houses just need an average of 10 kW to power everything. And because autos can create 40 kW of power, a car can become a power plant for the house or office. When individuals go to work to power the building, automobiles can also be plugged into a pole. This shift to a hydrogen economy provides a vital difficulty, and terrific opportunity of the 21st century.

Portable electronic devices such as laptops, video cameras and cellular phones can last 10– 20 times longer by utilizing hydrogen. In coming years, portable devices — such as laptops, cell phones, video recorders, and others — will require greater quantities of power for longer time periods. Fuel cells are extremely scalable and have simple charging abilities as compared to batteries. Mobile phone technology is advancing rapidly, however the limiting factor for the new technology is the power. Even more power is needed to offer consumers with all the functions in gadgets they desire and need. The military also has a need for long-term portable power for new soldier’s equipment. In addition, fuel cells operate quietly, and have low heat signatures, which are clear advantages for the armed force.

The building of the alternative energy market would quickly produce million jobs during the next 10 years. These jobs would include construction and operation of new power plants, manufacturing of renewable energy technology (such as solar and wind power), R&D for new renewable resource technologies, and jobs that are produced due to the money spent on these technologies.

In order to change our oil economy, we need to make an investment in changing it. We need to ensure that we are preparing how to power our world during the next 20 years and beyond.
